http://catalog.sierracollege.edu/course-outlines/esci-0015l/

Catalog Description Prerequisite: Completion of or concurrent enrollment in ESCI 15 Hours: 54 laboratory Description: Exploration of the ocean environment, including physical, chemical and biological aspects. Learning through investigation and systematic laboratory procedures. (CSU, UC) Course Student Learning Outcomes CSLO #1: Characterize ocean basin morphology in terms of bathymetric maps and profiles and analyze features in the context of plate tectonics. CSLO #2: Analyze modern and past marine sediment type and distribution. CSLO #3: Characterize ocean water properties (salinity, temperature, density) and relate them to each other and to oceanic processes such as upwelling. CSLO #4: Analyze water surface movement (waves, tides, currents) and its interaction with the coastline. CSLO #5: Describe the distribution and characteristics of life in the ocean.

Skill Demonstrations Example: Plot the track of a hurricane given latitudinal and longitudinal data; use the plot to calculate hurricane forward speed on any given 24-hour period. Repeatable No Methods of Instruction Laboratory Distance Learning Lab: Instructor facilitates construction of temperature vs. depth plots by showing a visual example and then checking as groups work collaboratively in constructing a similar plot in the lab handout. Instructor lectures briefly on the effect of human interference of beach drift and facilitates the analysis of case studies on the California coastline where groups of students work on the lab handout to evaluate each situation and describe in writing the known effects of particular man-made structures such as piers on beach growth or erosion. Typical Out of Class Assignments Reading Assignments 1. Read handout on marine sediments and apply information on classification. 2. Read handout on plate tectonics and work on boundary exercises. Writing, Problem Solving or Performance 1. Classify marine sediments based on the Ocean Drilling Project scheme. 2. Identify sedimentary layering from seismic profiles.
